5.2.3. PCI Express and PCI Capabilities Parameters

For each core (PCIe0/PCIe1/PCIe2/PCIe3), the PCI Express / PCI Capabilities tab contains separate tabs for the device, link, device serial number (EP), power management, VSEC, PRS (EP), MSI (EP), MSI-X (EP), PASID (EP), ATS (EP), TPH, PTM (EP), VirtIO (EP), LTR (EP), ACS (RP), slot (RP), and legacy interrupt pin register (EP) parameters.

Note:
  • (EP) = the parameter is only available when the IP is in Endpoint mode.
  • (RP) = the parameter is only available when the IP is in Root Port mode.
  • Otherwise, the parameter is always available.
